What color code are the flashback arrestors in an oxy-fuel cutting torch system?

In an oxy-fuel cutting torch system, the color code for flashback arrestors is standard to help ensure safety and proper usage. Flashback arrestors are typically color-coded red for acetylene and green for oxygen. These colors serve to easily identify the specific gas each side of the system is associated with; oxygen lines are marked in green, while acetylene lines are red. This differentiation is crucial because it helps prevent the dangerous potential of mixing gases and ensures that users maintain proper safety protocols when working with high-pressure gas systems. Color coding not only aids in the quick identification of gas types but also enhances overall safety in welding and cutting operations.
